Plex server showing incorrect on NAS

Plex Media Server NAS & Devices
1

Plex server running on Synology NAS (DSM 7.2) is working for hosts on my local network, however, I cannot launch it from the NAS itself. When I go into packages/Installed, where it shows my Plex Media Server running, it shows the URL of: http://nas.local:32400/web. My NAS do not know how to resolve this name to the IP of itself, nor is Plex server setup to allow http connections (only https). Is there a way to change this?

Check the hostname you’ve defined it as.

It should be hostname nas.

The domain it’s in, from the DNS resolver, is .local

My DS418 has a FQDN via the name server.

I’m not using QuickConnect (which does cause problems)

It looks this way, which is correct, in package center

Hi. Thank you for your reply. I believe the biggest part of my issue is what shows up in package center. It shows http://nas.local:32400/web vs the IP address. Is there any way to change that so it reflects the IP address for the URL in package Center vs nas.local ? Thanks again.

The attached screenshot shows the URL that my Plex server is running at. The issue is, that “nas.local” is only resolvable from my PC (Plex server is on a different internal network). Is there a way on the Synology was install of Plex Media Server, to change the url so it reflects the IP address of my NAS vs using “nas.local” as it shows today?

That URL is controlled by the DSM configuration itself.

The NAS is seeing itself as part of the .local mDNS domain and resolving that way.

Is there a way in the DSM configuration to change the URL to be the IP address?

You have to change the Syno’s config and take it out of the .local mDNS domain
-or-
Take it out of the mDNS server so it shows as a raw IP

Thank you. Would you be able to provide me some direction on how to complete these options? Thank you very much in advance.

Do you have Reverse Proxy involved?

From what I find, one way to do this is when using a reverse proxy and setting the hostname as nas.local

I’m also seeing a number of methods.

I don’t now your local setup.

Worst case is you could open a ticket to Synology and they’ll know precisely what best to do

If this applies to you, reverse the process.

My Synos are in at full FQDN domain which I manage.
The hostname I gave is is just the hostname ‘ds418’ without domain name included.

I get this:

Thanks. But I don’t use a reverse proxy. My setup is this:
Synology is on a separate network segment (different zone on my firewall) from my pc network. My pc/Mac is using a host file entry for nas.local to point to the ip address of the NAS. Nothing special setup on my nas besides the plex server install.

Thank you, you just detailed why you’re getting what you do.

  1. You’re running multiple subnets, This makes it “remote”.
    – This will matter a lot to Plex (Remote versus Nearby)

  2. Your host is defined as nas.local
    – It’ll always respond as nas.local because that’s how the URL ends up being forwarded to the Syno.

With both conditions, you’re going to have that separation and it will look like that.

Bringing it onto the same subnet will resolve the bulk of this.
Then, in your hosts file(s), drop the .local mDNS domain.

[chuck@lizum ~.2002]$ nslookup  ds418
Server:		127.0.0.53
Address:	127.0.0.53#53

Non-authoritative answer:
Name:	ds418.mydomain.tld
Address: 192.168.0.71

[chuck@lizum ~.2003]$

Here you can see my DNS resolves with the FQDN but the syno ignores it because they’re all on the same subnet.

Being in the same subnet makes a huge difference with Plex.

The segmenting I do here for personal vs plex is on hard, switched, VLAN ID boundaries.

My personal stuff / network is on VLAN ID 1.
Plex is on a different VLAN ID

Even though everything is on 192.168.0.x,
only my workstation port on the switch can see both VLANs and everything can get to the modem/router.
